The IP20 degree of protection (EN 60529) of the device is intended for a clean and dry environment. 8. Do not subject the Inline terminal to mechanical strain and/or thermal loads, which exceed the limits specified in the product documentation. 9. The Inline terminal has not been designed for use in po- tentially dust-explosive atmospheres. Installation in zone 2 1. Observe the specified conditions for use in potentially ex- plosive areas. 2. Install the device in a suitable approved housing (with at least IP54 degree of protection) that meets the require- ments of EN 60079-15. Observe the requirements of EN 60079-14. 3. In potentially explosive areas, the Inline terminal may only be snapped on or off and cables may only be connected when the power is switched off. 4. In zone 2, only connect devices to the supply and signal circuits that are suitable for operation in potentially explo- sive areas of zone 2 and the conditions at the installation location. Restrictions/limit values 1. Only Inline terminals that are approved for use in po- tentially explosive areas may be assembled on this Inline terminal. Before using an Inline terminal in a zone 2 potentially ex- plosive area, check whether it has been approved for in- stallation within this area. For a list of terminals that are approved for the potentially explosive areas of zone 2, please refer to the AH EN IL EX ZONE 2 application note. 2.
